What power source does a condenser microphone typically use?

A condenser microphone typically requires a power source to function because it relies on an electrically charged diaphragm and backplate to capture sound effectively. Phantom power or an internal battery are the primary methods to provide the necessary voltage for the microphone's operation.

Phantom power is a standardized method used in professional audio equipment, where power is sent through the microphone cable from an audio interface or mixing console. This method is often preferred for its convenience and efficiency, as it eliminates the need for bulky batteries. An internal battery is another option that allows for portability, enabling the microphone to be used in situations where phantom power might not be available, such as with portable recording devices.

Other choices, such as regular batteries, standard AC power, and solar power, do not provide the specific voltage requirements or the suitable connection method for most condenser microphones, making them unsuitable options for powering these devices.
